To all whom it mcvy concern:

Be it known that I, IRVING B. WELLING- TON, a citizen of theUnited States, and a resident of Los Angeles, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Apparatus for Sand-Blast Carving, of which the following is a specification.

My invention relates to the art of carving relatively soft materials such as wood by the use of sand blasts, and it is a purpose of my invention to provide an apparatus by which the carving of wood and like is economically facilitated and without requiring the employment of skilled workmanship as is incident to the methods and apparatus now in use.

It is also a purpose of my invention to provide an apparatus of the .above described character having embodied therein pattern members constructed so'as to be immune from the attack of the sand blast, and means capable of being readily assembled and disassembled for securing the pattern members in fixed positions on the work to be carved, and upon the completion of the carving of one piece of work they can be removed and applied to another piece of work without disturbing their positions one with relation to other. I will describe only one form of appara tus for sand-blast carving embodying my invention and will then pointout the novel features thereof in claims.

In the accompanying drawings,

Figure 1 is a' fragmentary perspective view of the different elements'comprised in one form of apparatus embodying my invention, the elements being disassembled but in their proper respective positions for assembling and with the pattern removed from a carved piece of work.

V Figure 2 is a fragmentary plan view of the locking templetembodied in the apparatus, the tem let' being in looking position and one-of t ev locking studs in section.

'Figur'e3'is a vertical sectional view taken onthe'line 3-3 of Figure 1 and showing the locking and positioning templets associated with the pattern and the three elements in -the'act of being applied to a piece of work.

Figure 5is a view similar tothat shown 111 Figure 4 showing the pattern in applied position tothe work and a blasting instrument in operative relation to the pattern and work. I

Similar reference characters refer to similar parts in each of the several views. 1 Referring specifically to the drawings, my lnvention in "its present embodiment comprises a pattern designated generally P and i made up of a plurality of elements of any desired design. In the present instance, I have shown a body element p, and two letter elements p, p the latter being positioned within the body element to co-operate therewith in forminga design for a sign. The several elements constituting the pattern are constructed of 'a' relatively hard lamination 15 preferably formed of metal, and a yieldable or compressible lamination 16 preferably formed of rubber. Each element is provided with a plurality of pins 17 which extend and are lived in the element so that their pointed ends project from the lower side of the element and function to position the pattern element upon a piece of work. Those portions ofthe pins projecting above the element serve as a means for holding the pattern element in fixed relation to the other elements whenassociated with a positioning templet T.

The templet T as shown in Figure 1 is in the form of a plate of suitable material preferably metal and is provided at suitable points with opening 18 in which the pins 17 are adapted to be received as clearly illustrated in Figure 3. This templet is also formed with larger openings 19 which are adapted to receive attaching studs'20 fixed. to and upstanding from the pattern elements. These attaching studs are formed with tapered freeends to facilitate their insertion into the openings 19 and the length of the studs is such that they project from the upper side ofthetemplet'for en ageinent'with a locking templet T. As s own in Figure 1' the locking 'templet T is in the form of a plate provided with openings 2 1Ito receive the studs and slots 22 communicating with the openings and permittin studs between thetwo. The studs 20 are ormed a movement of the templet on the so as to'eflfect a locking enga ement with recesses 20 which permit of the studs moving into the. slots 22. and. in at manner to locli the templet to the: studs. The templet T is also formed with relatively large slots 23 to accommodate screws. 2d, the screws havihg threaded engagement with openings 25 in thepositioning;templet and thereby serving to secure the locking templet to the positioning;templet-iby, allowing suiiicient movement of the locking templet to permite the studs; QQ-tonrmverintb or out of the slots 22.v

Int practice; the 1 several pattern elements 22, p ,,etc., eanzbe:locked-.toithe positioning templet through; movement of} the locking templet to. a: position in: whichlt-hea studs; 20 are disposed within the slots 22. l/Vith" the pattern elements looked: to thepositioned templct it will be clean that they' are see cured iii-fixed relative: positions and-ingsuch positions as to provide. the pattern forifornn ing. the desigm on; the work-- to, be canved: In Figure 3, the; pattern, elements are shown locked: to the positioning; templet and ready for application to; apiece of: work. indicated at: As. previously mentioned they apparatus is: designed and; used ini conjunction with relatively soft; material sucln asT wood or the like so that-1 the; pointed: ends of; the pin 17$ cantreadily penetrate? theworh and thus hold: the entire pattern: in. fixedi PQSl, tionupontlie-worle. lnzFiguref the pattern is shown applied to ithe worle with the pins in penetrated position; After? this operation the positioning; templet. can: be

During! the sand; blasting; operation, the pattern: is securely held against movement on the workzby: meanszofthe pins 1-7 so'zth'at the carving: of: the-work; can; be? accurately and expeditiously; canried. on, and without requiring; the: skill in; the manipulation of the:instmnnent, as. is=-necessary: with appara+ tus HGI'QtOfOIGrPlOPOSQdZL Asa previously: descrihed the; pattern elee ments includes a: yieltlah'le 01-" compressible lamination 16,- and. in: the: applied position of; the: patternto, thework: as shown; in Figure 5 thisdamination is, disposed uppermost; By virtuezofthe fact :thatit is: formed of, yieldable; on compressible material; it is immune from: the: attack: ofithe sand: blast; and in its overlying relation; with respect to thelowerlaminatiom 15;, it; I will be clear that: it: serves; a; protector tor: tllEE latter to prevent the sand blast impinging on and wearing away, the same.

After: aipiece of worliliasbeen carved as illustrated in Figure l, the pattern can be removed. from. the work and the elements thereofmaintained"in their proper relative positions. by, the:application of the positioning templet thereto, the studs 20 being again projected: into, the; slots 22 of the locking templet T so that when the two templets are lifted the pattern elements will: be elevated: from; the work and securely held against. movement; one with relation to the other? It will. thus: be"v manifest that the pattern elements: can be; appliedtas a. unit toua nother pieceoffworl; for-carving in the latter another" design and in this manner the pattern elements'can' be used "indefinitely on various pieces of work.
